Cockroaches

December 8, 2014

Family Structure

  • Female carries her egg until it is within 1 to 2 days of hatching
  • She deposits it in a sheltered area
  • Average: female produces about five eggs (range 4-8), averaging 30-40 eggs (range 18-50) each
  • Egg to adult: varies from 54 days to 215 days, with an average of about 103 days
  • Under lab conditions with a room temperature of 80 degrees F/27 degrees C and 40% relative humidity, only 50-60 days were required. This means one female could raise an average of 3 to 4 generations per year, but in warmer conditions, up to 6
  • Lifespan: 100-200 days (range 1-303)
  • Colonies are typically composed of at least 75% nymphs

Appearance

  • Adults: approximately 1/2″ to 5/8″ (13-16 mm) long
  • Light brown to tan except for two dark, almost parallel longitudinal stripes on the first segment of the thorax
  • Female darker color than male; broader abdomen as well
  • Nymphs: dark brown to black thorax with pale boundaries between the three sections of the thorax
  • Dark stripe located near each border
  • Eggs: Yellowish brown but usually two colors
  • Females have a paler end than the males
  • Eggs: approximately 1/4″ to 3/8” (6-9 mm) long, approximately twice as long as they are wide

  • Spend about 75% of their time in damp climates
  • To make entry, nymphs need about 1/32″ (1 mm); adults need about 3/16″ (5 mm) in width

  • Have been seen moving move from one building to another on occasion when it is warm
  • Although uncommon, they can survive outdoors during the warm months
